Let's change the mode of this kind of post, previously I have been providing the answer of NAGA right away, but this time let's start with screenshot with the NAGA decision hidden. Thanks for reading my blogs, and I hope you have fun here!

Game Review

East 2 Repeat 0: West, Dora 1s

 1.

What would you do? Push for Full Flush? Or fold?

Toimen, the dealer, declares riichi on 8m.We draw a souzu tile. If we discard 4p or 5p here, we’ll be 1-shanten for a full flush. What would you choose?

Let’s examine the situation more closely. Do we have any safe tiles?

• 5s → Genbutsu (already discarded, impossible to deal in to that player)

• 8s → Suji of 5s

• 6s → Half-suji of 9s

Now, looking at our hand, there are two possible paths:

1. Full Flush Route

We have an ankou of dora 1s, plus 33455 and 6778 shapes. If we cut 4p or 5p, the following draws can bring us to tenpai:

• 2s → Wait on 6s/9s

• 3s → Wait on 6s/9s

• 4s → Wait on 7s

• 6s → Wait on 2s/3s

• 7s → Wait on 4s

• 9s → Wait on 2s/3s

If we reach tenpai and choose not to riichi, this could still be around 10 han (chinitsu + dora 3 + pinfu or iipeikou).

2. Mawashi Route

We discard 5s this round to avoid ippatsu. This path likely tops out at riichi + dora 3.

The key decision: Do we aim for the massive hand that could give us a huge early lead and make the rest of the game much easier, or take the safer route to avoid immediate danger?

Both balanced and defensive NAGA chose to take the second route here.

That's quite interesting, and I acknowledge that the fact of the 6p tedashi before riichi is definitely not a good sign for the safeness of 45p. I chose to push here because I would like to win a big hand to have a deterministic lead. I'm curious about what you think about this decision making here?
